Title: Optical pick-up device
Inventor: NISHIHARA HIKARI
IPC: G11B7/12
Filed: 1988-08-03
Abstract: PURPOSE:To simplify the constitution of an optical pick-up device and to detect the exact inclination of a recording medium at a condensing point by using a hologram element, which diffracts a light, as an objective lens and guiding the reflected light of a light, excepting for a converged light on the recording medium, from the recording medium to a photo-detecting element. CONSTITUTION:A light to be outgoing from a laser light source 1 is diffracted by an objective lens 2 and a +1st order light 5 is condensed to a recording medium 4. Then, a 0-th order light 6 to transmit the objective lens 2 irradiates the recording medium 4 as a diffusing light. The +1st order light 5 is reflected by the recording medium 4 and transmitted again through the objective lens 2. After that, the light 5 is converted to the reproducing signal of information. On the other hand, the 0-th light 6 is reflected by the recording medium 4 and guided to photo-detecting elements 3a and 3b. The output signal of the photo-detecting elements 3a and 3b is sent to a differential amplifier, which is out of the optical pick-up device, and the inclining signal of the recording medium 4 is obtained by the arithmetic of the differential amplifier 7. In such a case, it is not necessary to provide a light source, which is separate from the reproducing of the information, for the inclination detection of the recording medium 4.

Title: Production of semiconductor device
Inventor: CHATANI MASAO
IPC: H01L21/336
Filed: 1990-07-23
Abstract: PURPOSE:To reduce the number o times of injecting ion and knotting exposure by leaving the etched back and inclined silica film implanting impurity ion of reverse conductive type, followed by using gate electrode and field oxide film as mask to implant impurity ions of reverse conductivity type. CONSTITUTION:Although residual silica film 6 reduces implanted ion energy and takes in ions, the residual silica film 6, when etched back, remains thick in the place which is in contact with the side of gate electrode 1, while on the contrary the thickness of the residual silica film 6 descends in the direction distant from the gate electrode. When implanting ions to the residual silica film from above, in an area where there is no residual silica 6, P<+>-type diffuse area 8 with a uniformly distributed high density of impurity is formed. However, in an area having residual silica film 6, as the film thickness increases, energy of implanted ion is weakened, and further since ions are also taken in the residual silica film 6, a p<->-type diffused area 7 is formed where the density of impurity continuously descends in the direction toward the gate electrode. As is stated above, after the gate electrode is formed, a p-type MOS transistor is formed having a LDD structure by carrying out knotting exposure once and ion implantation once.

Abstract: PURPOSE:To reduce the occurrence of un-wired lines in the automatic wiring of a surface mounted parts by generating a wiring returning back from via holes toward a surface mounted part pads and searching a wiring path with the wiring as a starting point. CONSTITUTION:When the surface mounted parts are automatically wired in a printed circuit board mounted with the surface mounted parts, via holes 111 to 118 are generated by drawing wiring 131 to 138 out of the surface mounted part pads 101 to 108, and the wiring 131 to 138 are returned back toward the surface mounted part pads 101 to 108 from the via holes 111 to 118 by the amount of a preliminarily determined distance by means of an algorithm preliminarily determined in a wiring layer at the back of the surface mounted part pads 101 to 108. The wiring path is searched with the termination of the wirings 131 to 138 returned back toward the surface mounted part pads 101 to 108 used as a start point. Thus, the wiring path generated at the back of the surface mounted part pads 101 to 108 can be prevented from interrupting the generation of the via holes 111 to 118 by drawing the wirings 131 to 138 out of the other surface mounted part pads.
